Actually, no. The problem is that you seem to enjoy sniping at threads and offering advice that you don't actually bother to back up.
Saying "it's physics" is a great get-out for you - much better than posting a link to somewhere that offers sound advice based on empirical evidence or industry guidance, or even your own experience (you've said nothing to back it up - it still doesn't mean you're wrong - and that's why I'm asking in the first place - but you aren't actually being helpful, don't you see that?).
Saying Lead Mate last 10 years, then a few years... how many years is it? ...while your point might indeed be valid it is actually belittled in value by your alarmist reduction in its lifetime over the course of a few thread posts.
I would certainly appreciate you not providing your 'input' to the thread any more. Try to take a few notes on how other folk respond in a helpful manner, you can certainly learn something. I'm here to listen to the forum... and, trust me, I
am listening and I
will be going back with some thoughts and I
am willing to spend more for a job I can be confident in - it's
why I'm asking so there's no point you saying I'm ignoring what I'm hearing - you don't know that, I'm just offering a counterpoint. You just rub me up the wrong way, I think. The problem is clearly with you, not with me.
